Pub Quiz #4

This picture is not from the place where we go for our pub quiz but it's one of the locals in my area. The Old Wheatsheaf also have a pub quiz on Thursdays and their jackpot is a mouth watering $500, but we go to the quiz at The Hemingford Arms in Islington. Tonight we got 23 points; the winners got 36. It wasn't our best result but a whole lot better than last week when I missed it due to my first night shift. I recruited another new member (also a McGill grad). Here are some of the questions from tonight's quiz:
a) How many points are there on the maple leaf on the Canadian flag (not including the stalk/stem)?
b) In what geological period did coal beds form?
c) Name two of the three longest bridges in Britain.
d) What instrument is the theme music in the TV programme QI played on?
e) Before the Euro was introduced, what was the name of the Portuguese currency? (question slightly modified)
f) What animal comprises 2 names where the 1st name describes the substance it interacts with, & is used to plough paddy fields?
g) Name the five elements made up of four letters.
h) What is the official name of the Old Bailey?
